Next: SERPS SandboxThe 'sandbox' is a much debated Google phenomena. SEOers have noticed that new sites that have already had lots of optimization, particularly inbound-links will rank highly for a couple of weeks in Google's results pages and then disappear for months. The theory behind sandboxing is that sites should acquire links organically, sites with lots of pre-existing links may be owned by spammers with lots of domains under their control. It is believed that Google sandboxes the site for a few months to see if it is a genuine new site with worthwhile content or if it has just been established to manipulate search results. The Freshbot can produce a similar effect. A site that is found by the Freshbot will appear in the Google index for a few days then vanish until it is picked up by the Deepbot later in the normal update cycle. The key difference with a sandboxed sites is that they are pre-optimized and often have a high potential PageRank due to inbound-links. It has been suggeste that sandboxed pages can be detected by adding seven nonsense exclusion terms after the target keywords in a Google query. As the nonsense terms will not appear in any page they should have no effect on the results but will in fact show the page in its pre-sandbox position. Some observers think they have spotted a reverse sandbox effect where sites with good content but with few inbound-links get high placement in the search engines results for a couple of months. This will give searchers the opportunity to make links to the site if the content really is good. It is a bit like the bookstore's new releases shelf, if the books are popular they will make it over to the bestsellers list. Inbound-Link SandboxSandboxing makes the black-hat technique of spamming disposable domains to the top of Google a riskier and therefore more expensive proposition. It will also discourage sites that buy high PageRank links as their effect will be delayed. Other commentators think that Google is now sandboxing all new sites. They will still be indexed but they will only begin to rank in results pages after a few months wait. This doesn't seem to be born out by experience, the author created a new site in October 2004 and had it ranking in the top 20 of Google results for a target keyword within one month. It could be that the sandbox is actually applied to inbound-links. The PR effect of inbound-links depending on age, IP address range (to detect link farms and cross linking and other factors. Beating the SandboxNo one knows for sure if the Google sandbox exists, but it seems to fit many search engine optimizer's observations and experiments. It is clear that with new domains expectations of quick results should be tempered. It may also be a good idea to get some reasonably optimized content onto a new domain as soon as possible before the full launch to overcome this initial delay. The sandbox has introduced some hysteresis into the system in order to restore a bit sanity to its results.
